  1. I cannot find the measurements for a Arduino/chipKIT Shield Connector to the Arty Z7 board which I need for my custom PCB I am drawing. Where can I find it or do I have to order the board first and measure it manually? /Fredrik
  2. I tried another @jpeyron, the HDMI, but it was old and needed to upgrade the IPs. But to upgrade the IPs I needed to "verify the changes" or something similar, which of coarse was impossible to do, so I came nowhere. I clicked the button which said the same thing (I should do), scrolled down the window with uninteresting text but I still couldn't upgrade them. I used the terminal in SDK, and I used the correct button to start recording. I'm still concerned about the DRAM, I cannot understand why I cant run the memory test on them.
  3. I'm downloading it but it is a long shot. I worked around the problem by not following the guide. Instead I added the files with ''Import Filesystem┬┤┬┤ and got the code running. However, it never finishes recording, i.e., a DMA S2MM event never happens. I also have one ZynQ system/project without any PL just to try the DDR3, using the example project you can find when starting the New Project Wizard. Its output is; Now I have no clue what do anymore nor time as it is getting really late. But there is something wrong with the memory now I believe.
  4. Thanks! Unfortunately that didn't help. This evening I will try building some of the other examples. Eventually I will try making my own simple project from scratch if this problem persists.
  5. I wanted to try the example Audio-DMA project but it went really bad. This is what I did and the output from Vivado and SDK 2017.4. Source the make_project.tcl. Update the ip because I must. Get eight critical warnings, e.g., [PSU-1] Parameter : PCW_UIPARAM_DDR_DQS_TO_CLK_DELAY_0 has negative value -0.050 . Generate output products. Generate HDL wrapper so I can extract the hardware. IIC ports names differ in the .xdc so I have to change them to capital letter (IIC). Also notice that the ja ports are there, I don't know why though. Generate the bitfile. Got 1715 warnings, mostly unconnected ports. Also about some unused sequential elements removed which can be bad. Export hardware with bitfile. Launch SDK and import 'Existing Projects into Workspace', i.e., the 'sdk' subfolder which yielded this; I see this in the guide; Many apparent errors at this stage can be solved by right-clicking the bsp project and selecting Re-generate BSP Sources. Ok, try; I can open the file in any text editor but SDK just shows a big red sign and 'Failed to create the part's controls'. There is also a small textbox where I can almost scroll around and see the content. In the problems tab I see this; If I comment that include out, this is shown instead; And that path do indeed not exist. Probably because that path does not exist, so doesn't the cpu_cortexa9 2.3 either. What can I possibly have done wrong, and what are all these Java errors? Is this something I should ask Xilinx about instead? Also, before this I tried the DRAM test program as a first thing. It failed so I thought I would just try something else in the meanwhile and this is what I got. Bad start for a new board =\.
  6. Solved by this: /opt/Xilinx/Vivado/2017.4/data/xicom/cable_drivers/lin64/install_script/install_drivers
  7. SDK says it is an unknown error but at the same time claims the cable is not connected to the host. I see both ttyUSB0 and 1. Vivado's autoconnect doesn't find it either, and is the only way I've ever used to connect to various boards.
  8. I have never had problems with FTDIs either. Thanks for the drivers anyway!
  9. I gave a fourth cable a chance, and now it worked, smh ^^ What's wrong with my cables these days? Now Vivado still cannot connect to it but that's another issue I guess.
  10. Already tried three different cables.

    Zybo Z7-20: FTDI DOA?

    Just plugged in my Zybo I got today and my Ubuntu installation cannot find it. Ok, so I made sure I am in dialout but that didn't help. Then I plugged it into my Windows computer but it cannot find it either. I have no more computers to try it on now except a Pi =/ Anything else I can do or is it broken? /Fredrik
